ROY K. BUNYON, OF SPOKANE. WASHINGTON, ASSIGNOR 0F ONE-HALF TO JOHN CART- MELL, OF SPOKANE, WASHINGTON nosr COLLECTOR App1icat1on filed August 19, 1929. Serial No. 388,838

My invention relates to dust collectors and more particularly to a dust collector that is adapted to be installed on a motor vehicle and connected with the air intake of the carburetor thereof whereby the dust is removed from the air before it is sucked into the engin'e. Certain objects of the invention are to provide bafiie means for forcibly projecting the air against a pool of oil whereby the heavier particles of dustare removed. Other objects are to provide a plurality of bafiie plates having felt linings and metal lathings having pockets that catch the finer particles of dust when the air is sucked through the carburetor. Further objects are to provide certain additional novel details of construction as hereinafter set forth.

With the above and other objects in view which will appear as the description procoeds, the invention consists of the novel construction, adaptation, combination and arrangement of parts hereinafter described and claimed. These objects are accomplished by devices illustrated in the accompanying drawings; wherein Figure 1 is a view in side elevation showing a portion of a motor vehicle with my device mounted thereon and connected with the carburetor thereof; 7

Fig. 2 is a view in exterior perspective of the dust collector;

Fig. 3 is an enlar ed view in perspective showing a section 0 one of the ba-flie partitions;

Fig. 4 is a view in vertical section taken substantially on a broken line 4, 4 of Fig. 2; and

Fi 5 is a view in horizontal section taken on a roken line 5, 5 of Fig. 4.

Referring to the drawings throughout which like reference numerals designate like parts, the numeral 5 indicates a housing having a cover 6 hinged" thereto at 7 and arranged to be locked in the closed position by a thumb screw 8. A gasket 9 or other packing is placed between said housing and cover to make this part of the device air-tight for reasons hereinafter apparent.

The housing 5 may be secured to the vehicle by means of'screw carrying lugs 10. Referring to Fig. lof the drawings, the device is ordinarily mountedon the dash or other convenient place in the forward part of the vehicle where it may be reached by the driver or operator thereof. A rubber hose 11 or other flexible connection extends from the air intake of the carburetor 12 to an outlet connection 13 of the lid 6 and an intake 14 for said lid provides means whereby air is drawn through the device at each suction stroke of the vehicle engine as will be underbaffle 17. A main baiiie partition 18 for said casing extends downwardly from the joinder of the intake 14 and outlet 13 in a forward slantwise direction to a point adjacent said flange baflie thus forming a restricted passage 19 therewith.

A plurality of curved bafile partitions 20 are disposed in spaced relation across said casing to form a number of conduits 21 that communicate with the outlet 13. Thus, when the air is sucked into the intake 14 it passes downwardly through the restricted passage 19 and isthereby projected with some force against a pool of oil 22 in the bottom of the housing 5 from whence it is deflected upwardly through said conduits to the carburetor. The impact of the air with the oil will remove the larger particles of dust and the means for removing the smaller particles of dust from the air will now be described.

Referring particularly to Fig; 3 'of the drawin s, the bafiie partition 18 as well as the ba es 20 are set in channel bars 23 that are secured to the sides of the casing 15. The bafiie 18 com rises a sheet metal backing 24 against which a felt pad 25 is placed and a metal lathing 26 of well known construction is secured against said ad. Pockets 27 are formed by the apertures in said lathing whose lower edges are bent outwardly thus providing effective means for collecting the finer articles of dust from the air when it is proected thereagainst as indicated by the direction arrows in Fig. 4 of the drawings.

The baflies 20 are similar in construction to the baflle 18 with the exception that the felt pads 25 are placed against both sides of the metal backings 24. The lathin 26 is likewise placed on both sides thereo against the ads and the upper edges of the pockets 27 are out outwardly for the purpose of catching the finer particles of dust from the air as it moves upwardly. By making these baflies curved it will be obvious that the pockets will engage the air more readily. It will now be apparent that the fine dust is efiectively caught in the felt pads and in. the pockets while the air is sucked through the device. The metal backings 24 grevent the air from passiing through the ba es as will be understoo \When the bafiies become saturated with dust the casing 15 may be removed and cleaned by submergin same in a bath of gasoline. The pool 0% oil 22 may also be drained ofi through a drain plug 28 and replaced by clean oil, anda drain cock 29 may be used for the pur ose of retainingthe oil at the proper level i desired. It will now be apparent that. I have provided an efiective means for removing dustatrom the air prior to its entry into the carburetor so that the fuel mixture will enter the vehicle engine in a clean condition.

Having thus described my invention, it being understood that minor changes in its construction may be resorted to without departingfrom its sc'opeand spirit, what I claim and desire to secure by Letters Patent of the United States is 1 1. A dust collector comprising a housing, a lid pivoted to the housing, air-tight gasket connecting means between the lid .and housa lid, an air intake and outlet for the lid, an inner casing open at both ends, the lower end portion of said casing contracted to form a ange bafile, said housin adapted to contain a pool of oil, a-main ba e partition for the casing slanting downwardly from the joinder of the air intake andoutlet to form a restricted assagewith the flange baflle, a plurality o curved baflle partitions for the casing spaced apart to form conduits communieating with the outlet, and said main and curved baflie partitions comprising a' metal backing and felt ads with apertured lath coverings arranged to form dust collecting pockets.

4. The combination with a motor vehicle and its carburetor of a dust collector comprisin a housin a lid an air intake for the li an air out et for the lid, a flexible conduit connecting said air outlet with the air intake of the carburetor, said housing adapted to contain a pool of oil, a main baffle partition arranged to direct the air from the air intake to the oil pool, a lurality of curved baffie partitions arranged to form conduits communicating with the air outlet, and each of said bafiles having .a plurality of dust collecting 'pockets.

In testimony whereof I aflix my si nature.
